Hulthen off-shell transition matrix for nuclear systems

P. Sahoo et al.

Summary: The exact analytical expression for the Hulthe off-shell Jost solution is constructed using the particular integral of the inhomogeneous Schroedinger equation. The Jost solution is utilized to calculate the off-shell physical solution and T-matrix for (n-p) and (n-d) systems, showing a correlation with its half-shell behavior.

Multipole polarizabilities for hydrogen-like atoms in Hulthen potential with and without spherical confinement

Yu Ying He et al.

Summary: In this study, the multipole polarizabilities for hydrogen-like atoms with Hulthen potential were calculated using the generalized pseudospectral method, producing precise results for energy states, transition oscillator strengths, and dipole polarizabilities. Additionally, quadrupole, octupole, and hexadecapole polarizabilities for both ground and excited states were reported for the first time, along with an investigation into the combined effect of Hulthen potential and an impenetrable sphere on polarizabilities. Comparison among different potential models revealed complex variations in energy corrections despite good agreement in ground state energies with the comparison theorem.
